The oval, which has undergone a $535 million overhaul, played host to its first AFL match on the weekend, drawing a crowd of more than 50,000.

The football fans also provided a major boost to city businesses before and after the fixture with reports that bars, restaurants and retail outlets enjoyed a surge in demand.

Mr Weatherill says that is expected to continue throughout the AFL season with hotels to also benefit from an increase in interstate fans.

"This really promises to revolutionise the winter economy of South Australia," Mr Weatherill said on Monday.

"When you realise what happened just this weekend and understand that will be replicated, to some degree, on every one of the next 20 weekends, you just see what an extraordinary boom this is for the city."

Mr Weatherill has also revealed the oval redevelopment will come in under budget, though by just how much will not be detailed until the state budget is delivered in June.
